عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: مِنْ كُلِّ اللَّيْلِ قَدْ أَوْتَرَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَانْتَهَى وَتْرُهُ إِلَى السَّحَرِ
Sayyida Aisha (may Allah be pleased with her) says that the Messenger of Allah (peace and blessings be upon him) performed the Witr prayer in every part of the night, but his (peace and blessings be upon him) Witr would be completed by the time of Suhoor.
